Headlight: Convenient for inspection and maintenance in dark environments and can also be used as a nighttime work light 3.) Design: Advanced visual design features a simple, dynamic, and colorful aesthetic Instructions: 1. Turn off the vehicle's ignition switch 2. Remove the blade-type fuse that comes with the tester from the socket. Then remove the vehicle fuse from the circuit to be tested and insert the tester's fuse into the electrical outlet to for ensure the correct circuit protection level. (Tester blade fuse rating: 20A/48V, standard) 3. Insert the tester's (select medium or small depending on the size of the blade fuse; if it's a small size, connect the small to the medium ) into the vehicle's fuse socket 4. If necessary, turn on the vehicle's ignition to energize the circuit. Then, turn on the tester (press the power button) and measure the current 5. The display will show the measured current of the circuit under test 6. When the display shows *DC*, the circuit under test is drawing positive current. When it shows C, the circuit under test is drawing negative current 7. After the measurement is complete, turn off the tester and press the power button again Replacement: If the symbol appears on the display, the battery is low and should be replaced. Before removing the battery cover, turn off the tester and for ensure that it is disconnected from any circuit Specifications: Part Name: Automotive Circuit Tester size: 110*45*30mm (Main Body) Model: CNBJ-611 Fuse Type: Standard Color: Sapphire Blue Material: ABS/PC Body Display: LCD Backlight: Blue Backlight Lighting: Front Lighting Battery Type: 1*23A 12V Battery Measuring Range: 0.01A-19.99A Maximum Load: 20A/48V (DC) for 10 seconds Current Accuracy: ±2% Operating Environment: -0°C - 40°C Relative Humidity ≤75% Storage Environment: -10°C - 50°C Relative Humidity ≤80% Package includes: 1* Automotive Circuit Tester A *gloves
